What is the use of higgs boson?

Answer 1

One might separate the answer into two concepts, firstly, the function of the particle in forces affecting matter - or particle interactions; and secondly its notional role in our understanding of the universe as expressed in the Standard Model. On the former point, the Higgs plays a significant role in the weak interaction crucial to fission and famously responsible for beta decay; and in some particles' acquisition of mass. On the latter point, the Higgs plays a role which can be said to complete the widely-accepted Standard Model predicted long ago. Lack of direct non-theoretical evidence of its existence is considered a major gap in particle physics which already has abundant evidence for other particles that constitute the Model. This effect gains the particle significant attention because of the perceived importance of resolving a crucial incompleteness in the Model which would be addressed by the particle's experimental verification. This problem inspired decades of research and the construction of one of the world's most complicated and expensive particle colliders, the LHC. Higgs theory explains the reason behind why certain particles evidence mass where, based on rules governing their interactions, they should have no mass. Considerable excitement was generated when studies of candidates produced in LHC collision events in 2012 seemed to verify particular properties of the Higgs including its predicted parity, spin, and mass-energy.

Answer 2

The Higgs boson is a fundamental particle that gives mass to other particles through the Higgs mechanism. Its discovery in 2012 confirmed the existence of the Higgs field, which plays a key role in our current understanding of particle physics and the fundamental forces of nature. Additionally, studying the Higgs boson helps scientists explore the origins of mass in the universe and the properties of the fundamental particles.
